Description

[Technical Field]

[0001] The present invention relates to a nurse call device such as a nurse call handset that constitutes a nurse call system. [Background technology]

[0002] BACKGROUND ART Conventionally known nurse call devices include those that are provided with a hook capable of hanging a target object such as a cable extending from another nurse call device or the other nurse call device itself (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-171530 Summary of the Invention [Problem to be solved by the invention]

[0004] In typical nurse call device usage environments, for example, when a patient moves or changes position in a bathroom or hospital room, the nurse call device or cable hanging from the hook can be pulled excessively. However, the above-mentioned conventional nurse call devices have the problem of being unable to respond when such a situation occurs.

[0005] Therefore, the present invention has been made in consideration of the above problems, and aims to provide a nurse call device that can resolve such situations when the object to be hooked on the hook is pulled excessively. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the invention described in claim 1 of the present invention is a nurse call device having a hook attached to a main body case, wherein a magnet is provided on at least one of the hook or the main body case, and the hook is attached in a state in which the attachment portion of the hook is attracted to the attachment portion of the main body case by the magnet. According to the invention of claim 1, a magnet is provided on at least one of the hook and the main case, and the hook is attached in a state in which the attachment part of the hook is attracted to the attachment part of the main case by the magnet, so that when a load greater than the magnetic attraction force is applied to the hook, the attachment part separates from the attachment part. Therefore, it is possible to provide a nurse call device that does not cause a situation in which the object to be hung on the hook is excessively pulled.

[0007] The invention described in claim 2 is characterized in that, in the invention described in claim 1, a hook is attached to the front of the main body case so as to be rotatable around an axis in the left-right direction, and the hook can change its position between an attachment position in which the attachment part is adsorbed to the attachment part and a detached position in which the attachment part is separated from the attachment part. According to the invention described in claim 2, the hook is attached to the front of the main body case so as to be rotatable about an axis in the left-right direction, and the hook can change its position between an attached position in which the attachment part is attracted to the attached part and a detached position in which the attachment part is separated from the attached part. Therefore, when a load greater than the magnetic attraction force is applied to the hook, the hook changes its position to the detached position, and it is possible to more reliably prevent a situation in which the attached part hooked on the hook is excessively pulled. [Effects of the Invention]

[0008] According to the present invention, a magnet is provided on at least one of the hook and the main case, and the hook is attached in a state in which the attachment part of the hook is attracted to the attachment part of the main case by the magnet, so that when a load greater than the magnetic attraction force is applied to the hook, the attachment part separates from the attachment part. Therefore, it is possible to provide a nurse call device that does not cause a situation in which the object to be hung on the hook is excessively pulled. [Brief explanation of the drawings]

[0010] Hereinafter, a nurse call handset according to one embodiment of the present invention will be described in detail with reference to the drawings.

[0011] FIG. 1 is an explanatory perspective view showing the front side of the nurse call handset 1 from diagonally above right. FIG. 2 is an explanatory perspective view showing the front side of the nurse call handset 1 from diagonally below right. FIG. 3 is an explanatory perspective view showing an exploded view of the hook 10 portion of the nurse call handset 1. FIG. 4 is an explanatory view showing a vertical cross section of the hook 10 portion of the nurse call handset 1. FIG. 5 is an explanatory view showing the hook 10 portion of the nurse call handset 1 from the right side when the hook 10 is in the detached position.

[0012] Nurse call handset 1 is installed on the wall of a bathroom or the like, and has a call button 3 on the upper front surface of main body case 2 that a patient can press to call a nurse, for example. Also, below call button 3 on the front surface of main body case 2 are a setting button 4 for synchronizing a handset (not shown) carried by the patient with nurse call handset 1, and an LED 5 for indicating the synchronization status. Furthermore, a hook 10 is provided on the lower front surface of main body case 2 to which, for example, the handset or a cable from another nurse call device can be hung.

[0013] Here, the mounting structure of the hook 10, which is the main part of the present invention, will be described. Hook 10 is a synthetic resin member molded into a roughly V-shape in side view, and includes a base 11 extending in the left-right direction, a tongue-shaped hooking piece 12 protruding obliquely upward and forward from base 11, and a plate-shaped mounting piece 13 protruding obliquely upward and rearward from base 11. Shafts 14 protruding outward to the left and right are provided on both left and right ends of base 11. Furthermore, mounting piece 13 has a recess that opens into its tip surface, and this recess serves as a magnet storage section 16 for storing magnets 15, 15.

[0014] Meanwhile, two mounting plates 20, 20 protruding forward are provided on the lower front surface of the main body case 2, facing each other on the left and right. The left-right distance between these mounting plates 20, 20 is approximately the same as the left-right length of the base 11 of the hook 10. A shaft hole 21 for supporting the shaft 14 is drilled at the lower tip of each mounting plate 20. Furthermore, a holding base 22, which is molded to protrude forward, is provided between the mounting plates 20 on the front surface of the main body case 2. The upper front surface of the holding base 22 forms an inclined surface 22a that slopes upward and rearward, so that it can abut against the rear surface of the mounting piece 13 when the hook 10 is in the mounting position described below. Additionally, an iron plate 23 is installed inside the main body case 2 at a location inside the inclined surface 22a.

[0015] The hook 10 is positioned between the mounting plates 20, 20 with the latching piece 12 positioned in front and the mounting piece 13 positioned in the rear, with both pieces 12, 13 protruding obliquely upward, and is attached to the front of the main body case 2 by pivotally supporting the shafts 14, 14 in the shaft holes 21, 21 in that position. Then, the magnets 15, 15 housed in the mounting piece 13 are attracted to the iron plate 23 of the holder 22, so that the hook 10 is held in an attached position in which the rear surface of the mounting piece 13 abuts against the front surface of the inclined surface 22a of the holder 22. Therefore, the hook 10 in such an attached position can be used by hooking the latching piece 12 onto an object to be hung, such as the handset itself or a cable extending from another device. However, in such a state of use, if a load greater than the attractive force of the magnets 15, 15 is applied to the hook 10, for example by pulling the object to be hung, the hook 10 will rotate about the axes 14, 14 so that the hooking pieces 12 fall forward, and the attachment pieces 13 will come off the surface of the holder 22. Then, the hook 10 will eventually assume a detached position in which the hooking pieces 12 hang down (FIG. 5), and the object to be hung will come off the hooking pieces 12 and fall. To return the hook 10 from the detached position to its original attached position, the hook 10 can be rotated by lifting the hooking pieces 12, and the attachment pieces 13 will come into contact with the surface of the holder 22 again.

[0016] According to nurse call handset 1 having the above-described configuration, magnets 15, 15 are provided on mounting piece 13 of hook 10, and hook 10 is attached with mounting piece 13 abutting on inclined surface 22a of holder base 22 by magnets 15, 15 being attracted to iron plate 23 built into main body case 2. Therefore, when a load greater than the attractive force of magnets 15, 15 is applied to hook 10, mounting piece 13 will move away from inclined surface 22a of holder base 22, and nurse call handset 1 can be provided that does not cause a situation in which the object to be hung on hook 10 is excessively pulled.

[0017] Furthermore, hook 10 is attached to the front surface of main body case 2 so as to be rotatable about an axis in the left-right direction, and hook 10 is capable of changing its position between an attached position in which mounting piece 13 abuts against inclined surface 22a of holder 22, and a detached position in which mounting piece 13 is separated from inclined surface 22a of holder 22. Therefore, when a load greater than the attractive force of magnets 15, 15 is applied to hook 10, hook 10 changes its position to the detached position, increasing the possibility that the object to be hung on hook 10 will come off hook 10, thereby more reliably preventing a situation in which the object to be hung on hook 10 is excessively pulled.

[0018] The nurse call device of the present invention is not limited to the above-described embodiment, and the overall configuration of the nurse call device as well as the configuration related to the attachment of the hook can be modified as needed within the scope of the present invention.

[0019] For example, in the above embodiment, the hook is attached so that it can rotate, but it is also possible to configure the hook so that it is attached only by the magnetic attraction force (i.e., the hook will fall off the main case when a load is applied). In addition, in the above embodiment, the hook is equipped with a magnet and the main body case is equipped with an iron plate, but it is also possible to configure it in the opposite way, with the hook equipped with an iron plate and the main body case equipped with a magnet, or there is no problem with configuring it with magnets on both the hook and the main body case.

[0020] Furthermore, the specific shape of the hooks can be modified in design, and it goes without saying that the number of hooks, attachment positions, etc. can also be modified in design. In addition, although the above embodiment describes a nurse call handset, the present invention can also be suitably applied to other nurse call devices, such as plate handsets installed next to a bed in a hospital room, as long as a hook is attached.
